This is a solution to my problem: as writing for me is always a struggle due to the tendency to keep more focussed on optimizing previously written text then on continue writing new. This app allows me to write like a flow.
This tool reminds me of the advice once given to NaNoWriMo participants (National Novel-Writing Month, super fun if you've never tried it in November). If you can't think of anything to write, just repeat "Ninja. Ninja. Ninja…" over and over again until you think of something. Just be sure to get words out and keep your mind-to-fingers connection nimble when first-drafting.
